If the driver is broken for mining, what do you expect cgminer to do about it?
no idea, its why I asked. Despite what my search said, I couldnt be the first one with the problem. I was genuinely hoping for a workaround or fix I missed.

updated to catalyst 13.4 from 13.1 last night. now cgminer (301 and 310) hangs on start. i get as far as this:
and it just sits there indefinitely. tried a few different .conf settings, and get ther same. without a .conf and specifying url and such, it crashes a few seconds after hitting return after entering password.
any ideas?

nobody? I'm to the point where im mining with guiminer, seeing ~150Mhs slower than i should be

Well I tried to search for this but came up empty. Currently solo farming for feathercoin when I see this: What does this mean? I solved for higher than the current diff. Did some one else beat me to the punch?
If blocks come in quickly on your altchain, and you were mining solo on your *coind then it doesn't have a way of telling you blocks have changed (like longpoll or stratum), so you risk mining on old blocks and increasing rejects. Lots of ways to improve this, someone else might have time to tell you.Code:
Rejected 000001f9 Diff 8.49M/5432796 BLOCK! GPU 1 pool 0
Thanks for the reply. I wondered if it was something like that. Must've been bad luck because I actually put in a second pool to get the longpoll... must've missed it by that much... Thanks for the great app

just what is "intensity"?
Did you see this?
--intensity|-I
and what does that mean? how does it affect miner output?
INTENSITY INFORMATION:
Intensity correlates with the size of work being submitted at any one time to
a GPU. The higher the number the larger the size of work. Generally speaking
finding an optimal value rather than the highest value is the correct approach
as hash rate rises up to a point with higher intensities but above that, the
device may be very slow to return responses, or produce errors.
NOTE: Running BTC intensities above 9 with current hardware is likely to only
diminish return performance even if the hash rate might appear better. A good
starting baseline intensity to try on dedicated miners is 9. 11 is the upper
limit for intensity while BTC mining, if the GPU_USE_SYNC_OBJECTS variable
is set (see FAQ). The upper limit for sha256 mining is 14 and 20 for scrypt.

Its like priority in the windows task manager, it sets how important the hashing is to the GPU. 'd' setting is good for computers being used while mining, while most dedicated mining cards see performance benefits in the 9-15 intensity range, from what I've seen.

Ok, thanks. Trying 45 seconds overnight for mincoins...
May 03, 2013, 06:19:50 PM
Con, can you address the best way to determine settings for scantime & expiry when mining the latest scrypt coins? Do you lower them to try to equal the block frequency? Like chinacoins were every second and mincoins are every minute, so it seems like leaving at default is a bad idea...
That's like going back to how we mined bitcoins >2 years ago before pools and longpoll. The answer is set the scantime as low as you can before the hashrate drops. If you're solo mining, something like 5s is usual for sha coins. However it can be slow to return results for scrypt so you'll have to experiment. May 03, 2013, 06:12:17 PM

Question: Is it a good practice to use "--scan-time 1" in cgminer?
I'm trying to solo-mine FTC (scrypt, 2.5 min/block) with GPUs. From what I can found, the usual recommended practice is to add stratum or longpoll pools to the list of pools, so cgminer will know when there is a new block.
However, from my own experiment, I found that existing FTC pools are slow to send out new block notifications. The following is a screenshot of cgminer running on 2 different machines.
http://i.imgur.com/AphbAkv.png
Machine on the left:
pools = [feathercoind, (stratum) feathercoin.is-a-geek.com, (longpoll) featherpool.com]
scan-time = 60
Machine on the right:
pools = [feathercoind]
scan-time = 1
Using "--scan-time 1" with a local feathercoind gives me new blocks detections 0-30 seconds faster than the stratum/longpoll connections (as seen above).
However, the statistics for the machine on the right show 60 new blocks (NB), 177 discarded work items (DW), and 1 rejected block (R). Having "DW > NB" and "R > 0" makes me feel that it might I may be doing something wrong. Naively I think that cgminer discards work only when a new block forces it to do so.
If anyone knows whether it's OK to use "--scan-time 1", and whether it's fine to have "DW > NB" and "R > 0", please let me know. Thanks!
